.To all whom-t may concern:

Be it known that l,A HARoLD FLn'roiinn 'lAYLoi-z, a citizen ol the United States, rcsiding at. Los Angeles, in the county of Los Angelesl and State of California, have invented a new and useful Rotary-Sprinkler 'llierinostatic Fire-Extinguisher, ot' which the following is a specification. v n object of this invention is to inake provision tor applying a fire-extinguishing iiuid to an incipient or other conflagration within a building or other conlined space.

The fluid for this purpose may be a carbon tetra-chlorid or tri-carbo or any liquid chlorin derivative that will produce chiorin gas sutlicient to destroy carbon combustion in the coniined space, and which will then prevent combustion of carbon with oxygen and fire.

An object of this invention is to provide means whereby a moderate isolated supply 0f the anti-combustion liquid niay be stored and may be discharged throughout a. pref determined space to produce a gas for sniothering ire confined between walls inelosing said space.

The accompanying drawings illustrate the y invention.

Figure 1 is an elevation partly in section and partly diagrammatic of apparatus constructed in accordance with this invention. Fig. i2 is a plan section of the rose nozzle on line indicated at afi, vFig. l.

The supply tank l may oe variously constructed and may be provided with an external or internal insulation to maintain an even temperature et the contents of the tank. internal insulation 2 is indicated in Fig. l. In case the tank l is wooden said insulation may be of cork or other suitable material cemented or otherwise fastened to the wooden walls by any suitable ineans.

Said tank ina y be tilled through a nipple 3 and afterward closed by a plug or cap il. An outlet pine controlled by the automatically close l valve '5 leads troni the bottoru otl the tank and is connected to a vertical pipe T forming the tubular stein. et a rotary sprinkling device as the sprinkler head 8. Said tubular stein discharges intoy the rotary sprinkler device S. Said device may be of any suitable forni, but is shown as a rose nozzle sprinkler head with perforations 9, l0 and l1 at its under side, topy side and periphery, so that when the sprinkier device is rotated rapidly the liquid contents thereof supplied to it troni the pipe will be 'thrown out through the outlets b v centrifugal iorce. To assist in this ettect the bottoni 9 and walls ot the circular nozzle S may be provided with iinpellers such as the upward projections a.

"the sprinkler S may be of any suitable character and may be rotated by any suitable means, such as a spring motor, a water motor or an electric inotor. .lP or convenience of illustration, an electric inotor is shown connected by a train i3 ot gearing to drive the tubular stein 7 oi' the sprinkler head or nozzle 8 into which liquid troni the supply tank will. be inducted. ls'hen the valve (5 is' open there is provided a free passage into pipe o.

It may be desirable to shut ott' the liquid supply between the pipe 5 and the top of tube T and with this object in view a governor valve ll controlled by suitable nieans is provided.

ln order that said governor valve mayl only open when the sprinkler head S has attained suiciently high speed to generate the required centrifugal torce to properly distribute the liquid, a centrifugal governor l5 or any suitable construction is connected to he rotated simultaneously vwith the sprinkler head S. so that when the head is rotating at a required speed the valve will be held open, but; will otherwise be closed. Thermostat eontrollml electro magnetic means are provided i'or setting the sprinkler into operation. With this object in view an electric circuit con'iprisingI a lead 1G connectcd to a tlierniostatic switch i7, and througl'i such switch with the lead 1.8 serves current to drive the motor l2 'from the Alower main j; whenever the circuit is coinpleted through the switch '17. Leads 19 to electro-magnet Q() ot' the valve (3 will open said valve simultaneously with the starting ot the. motor,

",lhe therniostatic switch i?. therefore oontrols the supply valve 6 and the inotor.

Any thermostatically operated nie-ans may be employed to open the valve 6 and to set the motor into operation, so that whenever heat is applied to the therinostatic means as by heat rising to the ceiling at 17, the circuit will be closed and the electromagnetic valve 6 will be opened and the motor 1:2 put-into operation, thereby .rotating the sprinkler ine head and operating the governor toopen the valve 1A so asto allow liquid to iiow tov the sprinkler head, whence it will be distributed by centrifugal force over a wide area. f It is intended thatv the ".liqudshaihbe of a character to expand' into a heavy combustion-preventing gas 'i vapor when discharged into the open air, so as to sink to exclude oxygen from the re that produced the heat that operated the thermostatic switch 17. f

The supply tank 1 is provided with an air {vent 22 that is normally closed by an automatically closed valve 23 controlled -loy electro-magnetic means, similar to that of valve 6, said means being energized through the leads 21 so that when the valve 6 is opened, the valve 23 will also be opened, and vice versa, so that liquid may flow from the tank4 when required, but the valve 23 will prevent evaporation from the tank when the liquid is 'at rest.

The pipe 5 is connected with sprinkler stem 7 by a hollow boX 24 in which the upper end of the pipe 7 is journaled to rotate.

The governor valve 14 may he'i/ariously constructed and arranged, and :in the instance vshown is of a cylindrical type having ports d adapted to slide intoregister with ports e of the valve chamberv 25,' and thus open communication from the pipe 5 to the stem 7. The valve controlling goverx nor 15 is connected with the sprinklerstem through gearing 26 to rotate the go/veinor according to the speed of the sprinkler; and the valve 14E is yoperativelv connected with said governor through va. ve steth 27 and lever 28 which lever engages with a slidable'sleeve29 adapted to be raised and lowered by the governor balls 30 in accordvance with the speed 'of the same.

The governor halls thus actuate the valve to open and close communication through the ports al and e in accordance with the speed of the sprinkler.

Let-naso will beallowed to flow into the nozzle, from whence it is distributed by centrifugal torce. When the fire is extinguished and the line, a motor for operating the sprinkler,

and a governor for regulating the low of water to the sprinkler.

2. A lire extinguisher comprising a rotary sprinkler head, a motor to rotate the sprinkler head, means to supply liquid to the sprinkler head, valve means to control said supply means, thermostatic means to control the valve means and the motor; a governor valve to control the supply ot liquid to the sprinkler, and governor' means to control the governor valve.

3. A ire extinguisher comprising a rotary sprinkler, a motor tol rotate the sprinkler,

means to supply liquid to the sprinkler,

valve `means to control said supply means,v

thermostatic means to control the valve means and the motor, a governor valve to control the supply of liquid to the sprinkler, and to control the governor valve.

Il. A re extinguisher comprising a tank, a rotary sprinkler on a lower level than the f tank, a pipe line connecting the sprinkler to the tank, a thermosta'tic'ally controlled valve in the pipe line, a thermostatically controlled vent in the' tank, and a governor for regulating the iiow of water to the sprinkler.

A fire extinguisher comprising 'a tank, a thermostatically controlled vent. for the tank, an outlet pipe for the tank, an electro? magnetic valve in the outlet pipe, a thermostat for controlling the valve, a rotary sprinkler to receive the flow of water from the tank through the pipe, a motor for rou tating the sprinkler, and a governor for regulating the flow.

In" testimony whereof, I have hereunto set my hand at Los Angeles, California,this 22d day of April 1916.
